This technical brief presents a new self-compensation hydrostatic spherical hinge to provide a large load capacity. The hinge consists of an upper part with self-compensation and a lower part with orifice restrictors. A comparative study of the static behavior is conducted between the self-compensation hydrostatic spherical hinge and the hydrostatic spherical hinge with orifice restrictors, the result shows that the self-compensation hydrostatic spherical hinge has an advantage in the static behavior over the hydrostatic spherical hinge with orifice restrictors, including a much larger load capacity, a smaller flow rate, and a smaller power loss.
